Circulating Exosomal microRNAs as Predictive Biomarkers of Neoadjuvant Chemotherapy Response in Breast Cancer
{.scrollable}
Neoadjuvant chemotherapy (NACT) |
an increasingly used approach for treatment of breast cancer |
Circulating Exosomal microRNAs(miRNA) |
small RNA molecules circulating in bodily fluids, potentially serving as biomarkers for treatment response after NACT |
Pathological Complete Response (pCR) |
absence of active cancer cells in a tissue from the tumor site after NACT |
Non-Pathological Complete Response (non-pCR) |
presence of active cancer cells in a tissue from the tumor site after the treatment |

to compare gene expression and gene interaction networks for pre- and post- treatment
to conduct differential expression analysis across pCR and non-pCR groups
to investigate whether circulating exosomal microRNAs could predict pCR in breast cancer patients treated with NACT
